psad Configuration

All psad daemons reference the file psad.conf within /etc/psad, and this file follows a simple convention where comment lines begin with a hash (#) mark, and configuration parameters are specified in a key-value format. For example, the HOSTNAME variable in psad.conf defines the hostname of the system where psad is deployed:

### System hostname
HOSTNAME                psad.cipherdyne.org;

Each value for a configuration variable must be terminated with a semicolon to denote the end of the value string. This allows comments to be included on the same line after the semicolon to aid in documentation, as in this example:

WHOIS_TIMEOUT               60;  ### seconds

Finally, psad variable values may contain subvariables that are expanded as psad parses its configuration. ...
